SHAFT AND AXLEl BEARING.

Speciication of Letters Patent.l

Application led March 31, 191.0. Serial No. 552,596.

To all whom 'it may concern: l

Be it known that I, FRANK MAXANT, a subject of the Emperor of Germanyand citizen of Austria-Hungary, residing at Chicago,

in the county of Cook and State ofIllinois,

have invented certain provenients in Shaft and Axle Bearings, of whichthe following is a specification.

This invention relates to improvements in roller bearings for shafts,carjaxles, ete. and the especial object of the improvements which formthe subject matter of this application for patentare as follows 2-to provide a roller hearing in which the members supporting the rollers willautomatically adjust themselves to any variation or deviation in theshaft or axle relative to the journal box carrying said bearings; toprovide a journal bearing which may be kept constantly supplied with oila-nd in which the oil will be fed to all parts of the axle or shaft andthe elements engaging same within the journal box; in which the rollersmay be free to rotate independently of each other and at the same timebe held in a fixed spaced relation to each other; in which the journalbox may be applied to a shaft from the sides of the shaft asdistinguished from being slid endwise over the shaft.

In carrying out the foregoing and other objects of general utility, Ihave produced a split journal box with which I have combined bearingrings' so mounted Within the box as to freely swing on a horizontalaxis, and have arranged in said bearing-rings, rollers which may rotateindependently of f eabh other and be free to change their relaf tivepositions within the journal box.

this application are modifications of bearings shown and described in my(ro-pending applicationunder Serial Number-530,431.

.In the accompanying drawing which forms a part of'this application, Ihave shown a preferred and a'modified adaptation of my invention in the'following v1ews:-

Figurel l is a longitudinal section taken through a roller bearing withits inelosing he particular improvements embodied in new and usefulImpending lugs formed on the box of a form adaptedn for use with lineshafting; Fig, 2 is a transverse section through Fig. 1 on the line 2 2;F ig. 3 is a View in elevation of one of rings which form a feature kofmy invention, the rollers being shownin cross-sec tion; Fig. 4 is alongitudinal section showing a slightly modified form of journal box anda modified arrangement of the roller* retaining rings; Fig. 5'is aAcross-section through Fig. 4t on the line 5 5; F ig.- 6 is anelevational view of roller retaining rings formed in two sections; Fig.7 isv al longitudinal section through a car axle box show# ing afragment of a car axle with my improved roller bearing applied thereto;Fig.

8 is a cross-section through Fig. 7 on the line 8-8, and Fig. 9 is anelevat-ion of a por-l tion of one of the roller retaining rings..

Referring to Figs. 1 to 3 inclusive, the-numerals 10 and 10a, representrespectively, the lower and upper sections of a journal box, which haveintertitting edges, and are provided with openings 10c for a shaft11,-indi cated in dotted lines in Fig. 1. 10b represents an opening inthe upper section 10a for the introduction of oil` 1()d representsdeinner walls `of the upper section 10L closed. l2 represents a`roller-supporting collar or ring which has on opposite sides,

4trunnions 12*i which are journaled in suitable recesses 109 in the boxsection 10. These rings are recessed at 12b to receive the end portionsof the roller 13. The overhang'ing portion 12c prevents endwise`movement of the rollers 13 in the direction ofsaid shoulder. Spacingrings 14 are formed with ooves lfla'in their inner ed e in which g1' g vgrooves are seated the rollers 13. One 4of these spacing rings is placedbetween lch Patented May 9, 191i.`

The collars have shoulders 19Con their outer eorrespending in forni and function to the shoulders 12Cabove described. The rollers i3 and the extensions 1G are constructedand arranged in the manner already pointed out. ln this 'form of "ournalbox, the sections may be applied Ato a shalt atr any point and when inplace be supported by any suitable hanger that Will en orarie thesections. ln-v asrnuch as the spacing rings are sealed in the internalgrooves oi the collars, the rings can. not be displaced so long as theshaft is in its bearings between the rollers Tal. l

Referring to 7 to E) inclusive, l have substituted a car-axle, andear-axle boi; lor l, to .3 inclusive, have omitted the lower is tion o'the collars. as it superlluous in t iype of journal bearing, the thrustbeing always upward, and have dispensed win the oirloW-blocks. Theaxle-boxes are of a welllnoWn' form, but are niade in a' lower section.20 and an interlitting upper section 2U", with the passage Q0 at one.end for the axle 2l, 'and an openingr 20 at the opposite end to insertthe usual packing andlubricant. The collars 22 are somewhat inert-thansemi eylindrie, the segment removed being' on line below the axis of theaide.
